To. all wzom t may concern.' Y

Be it known that we, HENRY Knnnsnnnn and ALLEN J. .VALrnn, citizens ofthe United States, residing at Mansfield, in the county7 .of Richland and State of Chio, have inble to an increase of temperature of the infected person when suffering with a feverish condition, and persons, having typhoid or other fevers, who are infected with gonorrhoea, will be freed from the latter disease.

My invention has for its object to provide means by which a localized feverish condition may be set up in the infected organ, and consists in the provision of a heating element adapted to be inserted in the organ with means for regulating the rtemperature of the element, and to indicate the temperature at all times.

Another object of the invention is the provision ofA an improved construction of surgical instrument of the type setforth by which sounds of different diameters may be employed in connection with vthe heating element for the most eifectualoperation of the device. Y

Another object of the invention is the provision, in connection with an electric heater, of an improved construction of means for controlling the resistance in the circuit in the heating element, by which an exceedingly fine adjustment of the resistance may be effected.

The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawings in which Figure 1 is a front view of our device, partly broken away, v

Fig. 2, a side view, partly broken away, and showing a fragment of a sound in position and partly in section,

Specification of Letters Patent.

Patented Dec. 20, 1921.

Serial No. 366,011.

Fig. 5, a plan view of the cover section of the resistance control casing,

F ig. 6, transverse sectional view of the resistance control and casing taken or. plane indicated by the line 6-6 of Fig. l, and

Fig. 7, transf-Ierse sectional view on a plane indicated by the line 7-7 of Fig. 1.

Referring to the drawings in which similar reference characters indicate corresponding parts throughout the several views, 1 '.idicates the base section of the resistance control casing of my improved apparatus and 2 the cover section thereof, said sections being made of insulating material such as rubber, fiber. or' the like, and held together in any suitable manner. as for instance by screws 3, as shown in Fig. 1.

Secured in base section 1 is a U-shaped frame 4;, by means of screws carrying a resistance coil 6,'and having a screw shaft 7 journaled therein and adapted to be rotated by a lrnurled wheel 8 secured to one end of said shaft. Wheel 8 is mounted in a recess 9 formed in the sections 1 and 2 of the resistance control casing and projects from the upper surface of Vcover section 2 to permit rotation thereof by the thumb or finger of the operator. The top surface of cover section 2 is formed with a transverse recess 10 surrounding the projecting edge of wheel 3 to provide for 'freedom of rotation of said wheel.

Mounted on screw shaft .7 is a nut 11 provided with a curved surface 12 that engages resistance coil 6, a laterally extending arm 13, and a vertically extending l.-shaped arm 14. Arm 14 extends into and is adapted to reciprocate in longitudinal slot 15 in cover section 2, while arm 13 is received in recess 15 in said section 2.

The lower end of sections 1 and 2 of the resistance control casing is provided with mating recesses forming an opening 17 for installing an electric cable 18 having one of the wires, forming one of the terminals of the circuit, connected with a conductor 19, secured to arm 13, at binding post 20, while the other wire is connected to one of the terminals 21 of a heater, hereinafter described, at binding post 22. The other terminal wire 23 of the heater is in circuit with resistance coil 6, the base section 1 being provided with recesses 24 and 25 toreceive said Wires l21 and 23 respectively.

The upper ends of sections 'l and2 of the resistance control casing areY provided with recesses 26 that are correspondingly threaded' toreceive the threaded end of a tubular casing 27. Casing 27 isV provided adjacent its lower end with anV L-shaped tube 28 communicating with the interior ot said casing and has mounted in its free Vend a clinical thermometer f 29, extended downwardly, and seated in' a recess 30 in cover section 2 that is parallel with slot l5 in said cover section.

Thermometer 29 is graduated as shown, and the :tace ofcover section 2 is also provided with graduations shown in Fig. l, and 3l indicates a double-ended pointer secured to L-shaped arm 14 to assist the operator in manipulating the apparatus.

rllubular casing 27 has one or more reduced portions 32 between the base vand the extended portion 33, the drawings showing but one of said portions 32, butV itwill be apparent that there may be two 0r more it desired, said reduced portions being provided to permit of the use of conventional sounds or" dierent diameters to conform to the dimensions of the orifice of the organ operated upon. Each of the reduced portions 32 and Vextended portion 33 is provided with diametrically arranged lugs or pins lthat are adapted to receive bayonet slots 35 in the ends of the sounds 36 for holding them in position on the heater' casing.

Mounted in extended )portion 33 of casing 27 is an electric heater 3f ot any well known type, no claim being made tothe construction of said element.V

ln Voperation the instrument Yis vinserted inthe orilice of Vthe organ to be treated, a soundV of proper diameter having been selected 'and the current isv turned on to set up an increase inthe temperature of the heating element 37. By observationrof the thermometer 29 and regulation of the re sistance by rotation of the lm urled wheel 8 use attachable to said portions, and said resistance being Vcommon to all of said sounds.

3. In a surgical instrument,V a casing, a

sound extending therefrom, a thermometer,V

a mounting means for the thermometer in communication with the sound, 4and said casing having a recess in which said thermometer is disposed.

t. In a surgical instrument, a casing, a frame within the casing, an electrical resistance means mounted by the frame, indicating means coperatingwith the resistance means having a movable part in circuit therewith, and means mounted by the frame to move said part.

`5. ln a surgical instrument, a casing in separable sections, a frame within the sections extending across the meeting faces thereof, a resistance coil mounted by the frame, a screw member mounted by the frame, a nut on the screw member in'circuit with the coil and one of the sections having an elongated slot into which the nut extends.

In testimony whereof we aix our signatures in presence of two witnesses.
